Thibodeau saddened by marathon tragedy

ORLANDO, Fla. -- Chicago Bulls coach Tom Thibodeau, who spent four seasons as an assistant with the Celtics, was saddened by the news of the explosions at the Boston Marathon on Monday.

"It's just terrible," Thibodeau said. "Our hearts go out to the victims, their families, the first responders, everybody there. It's just terrible. Very, very sad."

Two bombs exploded in the streets near the finish line of the Boston Marathon on Patriots Day, killing two people and injuring dozens more, authorities said. Various media outlets have as many as 70 to 100 people injured. Hospitals reported at least 105 injured, at least 15 of them critically.

Thibodeau knows how much the Patriot's Day celebration means to the people of Boston.

"It's huge," he said. "There's so much going on and the entire meaning of that day, it's so festive. It's unfathomable just to think about something like that happening there. Again, it's just a terrible day. Terrible."
